帶集成式放大板比例閥
首先,比例閥必須有一個配套的放大器,它接受來自于計算機,或者PLC,或者電位器(滑動變阻器)的控制信號,把0-20毫安微弱的信號放大到0-800毫安。計算機的信號太弱了。
然后,放大器把放大的信號傳送到電磁閥度,電磁閥依據傳來的信號大小,克服彈簧力,調節(jié)推桿的行程,輸出流量大約知1升/分鐘,壓力隨信號變化的控制油。
再后,控制油到達主閥芯的兩端,依據不同的壓力,推動閥芯移動相應的行程,因為閥芯本身有錐度的臺階,與閥體組合,不同的行程得到不道同的過流面積,再入版口壓力穩(wěn)定的情況下,得到不同的流量。終實現比例功能。
比例閥是由計算機(或其他),放大器,比例電磁鐵,錐度臺階的閥芯,入口壓力補償閥(單聯(lián)可以不要),梭閥,內置卸荷閥(把多余的流量送回油箱)等構成的一個體權系。才能真正實現比例功能。
